[1] All typical values are measured at nominal VCC(A) and VCC(B).
[2] tpd is the same as tPLH and tPHL.
[3] tdis is the same as tPLZ and tPHZ.
[4] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.
[5] fi = 1 MHz; VI = GND to VCC
